Comment 1 for bug 1650285

Bug normally should be invalid due to enough iron available in the smithies. One need just to remove the iron from them or they will use all of it for weapons.

However AI will need some iron on the map to be able to build a ship. starting iron won't help it. Iron needs to be discovered lately, to have a chance having a port constructionsite already.

So either we skip iron for the barbarian port, we add some iron to the map, or we just set AI Players to empire or atlanteans or frisians
